niUSRP 2920 FM Auto Tuner

[n'mish]

Hello,

I am trying to improvise on NI provided FM demodulation example, in which, I am trying to create auto tuning feature and store available FM channels in [0-9] 1-D array for 10 preset stations. Do I need to design my own driver as I am not able to pass niUSRP Rx configuration driver in a loop. The errors that I am getting states that the niUSRP Configuration driver should be initialized and not running.

Any ideas how I might be able to sweep through 88.1MHz to 108MHz and store 10 present stations? I have not received permissions to share my .vi, thus I am limited to descriptions only.

Thank You

Use the property node for LO and carrier frequency. There is a shipping example that uses these functions.

Do you know the name of the shipping example? I desparately need answer by tomorrow.

I found the shipping examples: 

"niUSRP EX Fine-Tune LO Frequency.vi" and

"niUSRP EX Rx Continuous Async Reconfig on the Fly.vi"

useful.

Thank you so much for right direction.
